The air conditioner is installed 75 mm from the ceiling: will a wooden cornice KZ-010 with a height of 66 mm fit and will there be a service gap left

The indoor unit of the air conditioner is already mounted on the wall. From its top point to the ceiling — 75 mm. After installing the climate equipment for the room, KZ‑010 was chosen: a wooden ceiling cornice with a cross-section of 66×51 mm. On paper, it seems the profile fits:

75 − 66 = 9 mm.

But this arithmetic answers only one question: whether two stationary geometric lines will intersect if 66 mm actually occupies the wall section from the ceiling downward. It does not answer whether the air conditioner, after installing KZ‑010, can properly draw in air, open its front cover, release filters in the required direction, and be serviced without dismantling the cornice.

Therefore, the direct answer is:

You cannot buy KZ‑010 just because 9 mm remains after subtraction. The cornice can be run above the already installed air conditioner only when the instructions for the specific model allow the actual top clearance after finishing, the air intake remains free, the cover opens fully, the filters are removable, and the service technician gains access to the unit. If at least one condition is not met, KZ‑010 must be ended before the air conditioner, resumed after it, or a more compact top line should be chosen.

This is especially important because the air conditioner is already installed. Moving the indoor unit for a decorative profile is a separate technical job involving the line, drainage, and electrical work. So, first check the existing air conditioner, and only then buy the cornice.

Order procedure:

1. record the exact model of the indoor unit;

2. find the manufacturer's installation and service instructions;

3. check the required space above and on the sides;

4. measure the actual 75 mm at several points;

5. place the full-size template KZ-010;

6. open the front cover;

7. remove the filters as required by the specific model;

8. check the upper air intake;

9. determine whether the cornice can be run continuously;

10. if not — design two clean ends and recalculate the 2400/2600 mm planks.

If the profile has not been finally selected yet, you can first Buy wooden ceiling baseboard after checking more compact options. If KZ‑010 is chosen specifically, the solution is built around its actual cross-section and the installed air conditioner.

Wooden cornice KZ-010 66×51 mm: what dimensions and prices are confirmed by the product card

The current STAVROS product card shows three main product lines:

KZ‑010 version	Size, mm	Price at the time of check	Availability at the time of check
MDF	66×51×2600	3,140 RUB	SPb — 82 pcs.
Beech	66×51×2400	7,200 RUB	St. Petersburg — 44 pcs.
Oak	66×51×2400	11,120 RUB	St. Petersburg — 14 pcs.

The card also confirms the "Prestige" quality, for MDF — the "Under enamel" preparation, one-click purchase, rigid packaging frame 390 RUB, and the average production time for an unavailable item made to order is 5–10 working days. Prices and stock are updated, so they need to be re-checked before payment.

The first product mention is — Wooden Cornice KZ-010.

Which two sizes are important near the air conditioner

In the original KZ‑010 scheme, the 66 mm size is used as the height of the cornice along the wall. That is why with the top of the air conditioner at 75 mm, a nominal gap occurs:

75 − 66 = 9 mm.

The second cross-section size — 51 mm — describes another dimension of the profile. It also cannot be ignored, because the volumetric cornice protrudes from the wall plane and can get in the way of the opening lid or filter. The exact orientation of the cross-section must be verified against the drawing and the actual template before installation.

Why 66 mm is not "just a decorative height"

In a regular room, the profile can only be assessed by proportion.

Above the air conditioner, these 66 mm become part of the technical unit:

• the lower edge of KZ‑010 ends up almost at the housing;

• only 9 mm of nominal field remains;

• any manufacturer requirement for free space may exceed this value.

Why 2400 and 2600 mm will be considered after the service node's decision

If KZ-010 runs continuously above the air conditioner, the wall is considered one segment.

If the cornice is interrupted at the unit, one long line turns into at least two parts:

• to the left of the air conditioner;

• to the right of the air conditioner.

So, the decision on the service directly changes the number of planks.

Wooden ceiling plinth and air conditioner: three different types of gap

The phrase "9 mm remains between the air conditioner and the cornice" is too rough. It is useful to distinguish three values.

Geometric gap

This is a simple difference:

Ggeo = D − H

Where:

• D — the actual distance from the ceiling to the top point of the indoor unit;

• H — the wall height KZ‑010.

In our example:

Ggeo = 75 − 66 = 9 mm.

Air gap

This is the space that a specific model needs for standard air intake.

It is not derived from the KZ‑010 size. It is taken from the air conditioner's instructions and checked on the actual unit.

Service gap

This is the space required to:

• lift/remove the cover;

• remove the filters;

• remove the decorative panel;

• gain access to the fasteners and connections.

It may be larger than the air gap.

Why you can't choose the maximum "by eye"

Different indoor units have:

• different cover shapes;

• different air intakes;

• different directions for removing the filter;

• different service operations.

Therefore, the only safe universal recommendation is to use the instructions for the specific model.

Our factory also produces:

KZ-010 occupies 66 mm: what the remaining 9 mm actually means

Nine millimeters confirm only one thing:

if the top of the block is indeed exactly at 75 mm, and KZ-010 in its working orientation occupies 66 mm of the wall, the static dimensions nominally do not overlap.

But it does not follow from this:

• that air passes freely;

• that the front panel opens;

• that the filter comes out;

• that the service technician can work;

• that the manufacturer's instructions allow such installation.

Why 9 mm is especially sensitive to error

If the 75 mm distance is measured:

• along the decorative cover;

• at only one point;

• to an uneven ceiling,

the actual minimum may be less.

For example:

• on the left — 75 mm;

• in the center — 73 mm;

• on the right — 71 mm.

Then, at the same 66 mm, nominally remains:

• 9;

• 7;

• 5 mm.

The minimum point is critical, not the average value.

Why the gap may change after finishing

The actual position of the cornice depends on:

• the mounting layer;

• wall unevenness;

• final fitting;

• ceiling geometry.

Therefore, the final test is carried out on a real template in the design plane.

Why air conditioner instructions are more important than universal advice about 5, 10, or 20 mm

For wall-mounted split systems, there is no single top clearance value that can be safely applied to any model.

Requirements differ across manufacturers and series. They are related to the design:

• air intake;

• heat exchanger;

• cover;

• filter;

• mounting plate.

Therefore, the article does not prescribe:

"leave at least 10 mm"
or
“9 mm is definitely enough.”

Correct order:

air conditioner model → manufacturer's instructions → required space → actual KZ-010 template.

What to look for in the instructions

Sections:

• installation clearance;

• minimum space;

• service space;

• filter removal;

• front panel removal.

If the instructions are not available in Russian, use the official manufacturer's documentation for the exact model/series.

Why an example of a different model is only an illustration

Even if a similar wall-mounted unit specifies 80–90 mm on top, that does not become a requirement for your air conditioner.

Such an example only proves that the nominal 9 mm cannot be declared a working clearance without a data sheet.

Where the indoor unit's air intake is located and why KZ-010 may interfere

For wall-mounted units, air can be taken in:

• through the top grille;

• through the upper-front part;

• through a combined zone.

The exact location depends on the model.

If the air intake is on top

KZ-010 ends up directly in the potential air supply zone.

Even without physical contact, the cornice can reduce the free cross-section above the unit.

If the air intake is shifted forward

The risk may be lower, but the actual airflow and documentation requirements need to be checked.

What not to do

You cannot evaluate the air intake based on a photo of a similar air conditioner.

Externally identical units may have different internal aerodynamics.

Practical check

Remove the filter or open the standard top part according to the instructions and see:

• where the suction grille is located;

• which area above the housing must remain free.

How the air conditioner cover opens and why a cornice may only interfere during maintenance

In daily operation, the indoor unit may cool the room perfectly, and the conflict will only appear during the first cleaning.

Front cover of different models:

• lifts upward;

• folds back;

• removed after lifting;

• has locks in the upper zone.

Why this is a dangerous "hidden" incompatibility

With the lid closed, there is 9 mm between KZ‑010 and the block.

But at the moment of opening, the top edge of the lid can describe an arc and enter the volume of the cornice.

How to check without guessing

1. Install the KZ-010 template.

2. Slowly open the lid.

3. Record the maximum angle.

4. Check removal, if provided.

5. Repeat closing.

What to consider a negative result

If opening requires:

• bend the lid;

• move the block aside;

• remove KZ-010;

• leave the lid not fully open,

the cornice in this configuration is not suitable.

Air conditioner filters: can they be removed with KZ-010 above the block

Opening the lid does not mean servicing the air conditioner.

Filters can be removed:

• up;

• upward and toward you;

• at a slight angle;

• after additionally releasing the latches.

The installed cornice may not interfere with the lid, but it can block the filter's trajectory.

Checking the filter on a real model

You need to not simulate the movement with your hand, but remove the filter in the standard way.

With template KZ-010:

1. open the front panel;

2. release the filter;

3. remove it completely;

4. return it back;

5. close the lid.

If the filter bends only because a cornice appeared above the unit, the service node is bad.

Why you shouldn't rely on filter flexibility

The filter may be plastic or have a frame. Forcing it to bend:

• is inconvenient;

• increases the risk of damage;

• does not match the standard procedure.

What else to check

If the unit has:

• additional filter cassettes;

• a decorative top cover;

• sensor;

• Wi-Fi module,

their maintenance must also remain accessible.

Why you shouldn't close the air intake with a decorative cornice

If a specific indoor unit takes in air from the top, the free space above it is part of the system's operation.

KZ-010 should not become a "canopy" that is brought almost flush with the inlet grille.

What may change with too tight a proximity

There is no need to promise specific percentages of power loss. Technical logic is sufficient:

• free air inflow decreases;

• operating aerodynamics differ from what the manufacturer intended;

• the unit may run noisier or abnormally;

• Maintenance becomes more difficult.

What counts as proof of compatibility

Not an opinion:

"there is a gap between them."

And simultaneously:

• manufacturer's instructions;

• actual geometry;

• Free grille;

• standard opening;

• standard maintenance.

Full-size template KZ-010: how to check 66×51 mm before purchase

With only 9 mm remaining, the mockup is especially useful.

You need not a 66 mm rectangle on the wall, but a volumetric cross-section template of KZ‑010.

What to make it from

• thick cardboard;

• foam board;

• plywood;

• MDF.

What to reproduce

Minimum:

• 66 mm along the wall;

• the second profile dimension is 51 mm;

• working position in the corner of the wall and ceiling.

Where to place

Across the entire area above the air conditioner, not in a single spot.

Also check:

• left edge of the unit;

• right edge;

• route exit point;

• nearest inner corner.

What to do after installing the template

1. turn on the air conditioner;

2. visually check the air intake;

3. open the cover;

4. remove the filter;

5. check access by hand;

6. look at the unit from the side.

Why a template is stronger than 3D visualization

Visualization rarely knows:

• the exact model of the block;

• the real cover;

• actual ceiling;

• installation misalignment.

The mockup shows the existing object.

Three options for passing KZ-010 near the air conditioner

After technical verification, three basic solutions remain.

Scenario	Appearance	Service	Cutout	When to choose
Continuously above the block	Solid top line	only if full access is preserved	easier along the wall	The instruction and layout confirm
Interruption before the block and continuation after	Two clean ends	good access	The wall is divided into 2 segments	the cornice is too close
break in the top line across the entire AC zone	The unit reads as a technical zone	maximum access	Fewer short fragments	two small segments would look random

the cornice runs continuously above the air conditioner

This is the best option visually, but the most technically demanding.

Terms:

• top clearance is allowed by the manufacturer;

• the air intake is clear;

• The lid opens;

• filters are removable;

• the unit can be serviced.

One point of "does not touch the housing" is not enough.

KZ-010 ends before the air conditioner and starts after it

The most direct way to preserve technical freedom.

Two visible endings appear that need to be made identical.

The top line does not pass over the air conditioner zone at all

Sometimes it is aesthetically cleaner than two short segments of 100–200 mm near the unit.

Especially if the air conditioner:

• is located close to the corner;

• located above the window;

• is connected to the route/duct.

Where to end KZ-010 before the indoor unit

The ending point should not be arbitrary.

You need to look at the following simultaneously:

• the edge of the air conditioner housing;

• a window;

• the casing;

• the nearest corner;

• the route;

• lighting fixtures.

Straight end

The simplest solution.

requires:

• clean cut;

• preparation of a fresh end;

• finish.

Return to wall

Short part closes section KZ-010.

Looks more architecturally complete, but:

• complicates cutting;

• requires additional material;

• creates miter joints.

Vertical end of the air conditioner

You can finish the cornice along the external vertical of the block if it looks intentional and does not interfere with the route.

Offset from the housing

Sometimes it is visually better to leave a wall field between KZ‑010 and the air conditioner.

But a universal offset size is not assigned: first the service zone, then the composition.

If KZ-010 is interrupted, the two sides should look like one unit

If the cornice approaches the air conditioner from the left and right, the endings are perceived as a pair.

Check:

• same height;

• same type of end;

• same offset;

• identical finish.

When symmetry is not required

If the air conditioner is located close to the corner.

For example:

• to the left of the block 300 mm of wall;

• to the right 1800 mm.

Then two identical short segments may look worse than an asymmetric but architecturally justified solution.

What matters more

Not "mathematical symmetry," but a clear compositional reason.

Can KZ-010 be run behind the air conditioner

For an already installed unit, this is a weak idea.

Theoretically, the cornice could have been provided behind the mounting plate before the air conditioner was installed. But if the unit is already mounted:

• removing it for decoration;

• interfering with the route;

• changing the mounting plate

cannot be recommended automatically.

When this is generally discussed

Only if:

• the service organization confirms dismantling/installation;

• makes sense by design;

• manufacturer requirements are maintained.

Why 'hiding the profile behind a block' doesn't solve 9 mm

The cover and air intake are still in front of the cornice.

Additionally, the area behind the indoor unit may become inaccessible for maintenance.

Air conditioner hangs above the window: how to coordinate KZ-010, trim, and window top

Several horizontal lines usually converge above the window:

• the ceiling;

• KZ‑010;

• top of the air conditioner;

• window trim;

• curtain rod;

• route.

If you design each one separately, you get visual noise.

First, determine the dominant line

For example:

• KZ-010 runs along the entire room;

• the window has its own casing;

• the air conditioner becomes a technical break.

Or vice versa

If the block occupies almost the entire area above the window, the cornice may end before the window composition.

What not to do

There is no need to leave a short KZ‑010 of 120–180 mm between the window corner and the air conditioner just for the sake of formal continuity.

Such a fragment may look like a cut-off piece.

The air conditioner route goes upward: what to do with KZ-010

The general topic of routes is already covered in the material how to style an air conditioner and its route in the interior.

For KZ‑010, one specific question needs to be resolved:

whether the route crosses the mounting zone of the profile.

If the route goes upward next to the block

Need to know:

• width of the duct;

• protrusion from the wall;

• access to connections;

• whether the decorative box can be removed.

Why you cannot "cover" the KZ-010 route without checking

The profile may:

• block access;

• not sit flush against the wall;

• require a deep cut.

What to do

First the route and service.

Then — the decorative line.

Why you cannot cut a deep niche in KZ-010 for a cable route without checking the profile

If the route box intersects with the cornice, there is a temptation to simply cut out part of KZ-010.

This is risky for a profiled product.

What changes with deep cutting

Allowed:

• disrupt the face pattern;

• weaken the edge;

• expose the internal MDF structure;

• get an asymmetrical shape;

• complicate the corner joint.

When local trimming is generally acceptable

Only after:

• drawing;

• section check;

• approval with the foreman;

• understanding which section remains load-bearing.

Why it's better to decide the route first

If a decorative box can be made narrower or moved to another plane, it's often cleaner than turning KZ‑010 into a custom-cut profile.

KZ-010 from MDF under enamel: when an interruption near the air conditioner is easier to handle

MDF KZ-010 has dimensions:

66×51×2600 mm.

Current price at the time of check:

3,140 RUB.

The card shows the preparation "Under enamel."

This is convenient if the cornice needs to be visually blended into the ceiling or wall.

Why MDF is convenient with two open ends

After interruption near the air conditioner, two ends appear.

They can be:

• prepared;

• prime;

• painted in the same system.

But enamel does not fix a bad service unit.

If the air conditioner cover does not open, white paint does not make a 9 mm working gap.

First mechanics, then color.

Can you make a cornice in the color of the air conditioner?

Technically, you can pick a close white, but the housing of climate equipment and painted MDF have different:

• textures;

• shine;

• plastic/wood-composite.

It is better to solve the composition through the common color of the wall/ceiling, rather than trying to imitate the plastic of the unit.

Oak KZ-010 next to a white air conditioner: when natural wood is justified

Oak KZ-010:

66×51×2400 mm.

Price at the time of check:

11,120 RUB.

Natural oak next to the white indoor unit creates a strong contrast.

It works if the interior already has:

• oak doors;

• furniture;

• panels;

• the floor skirting board.

For such a scenario, it is logical natural wood baseboard as part of the overall molding language, but KZ-010 remains a cornice, not a baseboard.

If KZ-010 is interrupted at the white block

The exposed oak ends will be more noticeable than painted MDF.

You need to decide in advance:

• straight end;

• return;

• tinting of fresh cut.

Why wood needs to be distributed before cutting

On the left and right of the air conditioner, two parts are perceived as a pair.

If one is noticeably darker, the asymmetry is enhanced by the white body between them.

Beech KZ-010 under enamel: a compromise between solid wood and a painted line

Beech:

66×51×2400 mm.

Price:

7,200 RUB

It can be rational if solid wood is needed, but the final surface will be opaque.

By cutting

Beech has the same length of 2400 mm as oak.

Therefore, all quantity calculations for wood versions are identical in geometry.

By finish

A fresh end after interruption can be prepared for enamel.

But the base remains wood, so the craftsman must consider its behavior and the coating system.

KZ-010 2600 or 2400 mm: the air conditioner changes the wall cutting map

If the cornice runs continuously, the wall is one piece or several sequential strips.

If the block creates a break, one line turns into at least two independent segments.

Example of a 4600 mm wall

For example:

• to the left of the air conditioner service zone — 1700 mm;

• to the right — 1650 mm;

• the remaining central zone is occupied by the block and necessary clearances.

Sum of KZ-010 on this wall:

3350 mm.

MDF 2600

One plank is not enough.

Two give:

5200 mm of source material.

You can create:

• 1700 from the first;

• 1650 from the second.

Remainders:

• 900 mm;

• 950 mm.

Beech/oak 2400

Also need two planks.

Remainders:

• 700 mm;

• 750 mm.

Why the same number of planks does not mean the same economy

MDF leaves longer remnants that can cover adjacent short walls.

But the material is different, so "2600 is better" is not a universal conclusion.

How to use the two leftovers after bypassing the air conditioner

After the wall from the previous example, the following remain:

MDF:

• 900;

• 950 mm.

Wood:

• 700;

• 750 mm.

They can become useful if the room has short segments.

Suppose there are sections nearby

• 850 mm;

• 720 mm.

For MDF, both are covered by leftovers.

For a 2400-mm wood board:

• 750 covers 720;

• 700 does not cover 850.

Need a new whip or another overall map.

What the example shows

The air conditioner changes not only the length of the wall, but also the structure of the remainder.

Therefore, the entire room must be calculated together.

Why the room perimeter is no longer suitable for calculating KZ-010

Let's imagine four independent segments after all breaks:

• 1700;

• 1700;

• 1700;

• 1700 mm.

Total length:

6800 mm.

For MDF 2600

Pure arithmetic:

6800 / 2600 ≈ 2.62 → 3 planks.

But two parts of 1700 do not fit into one plank:

1700 + 1700 = 3400 > 2600.

Each part requires a separate strip.

Actually:

4 slats.

For wood 2400

Arithmetic:

6800 / 2400 ≈ 2,83 → 3.

Practically:

again 4, because two parts of 1700 do not fit together.

This is a classic conflict of "length and cutting"

The quantity is determined not by the sum, but by the set of whole parts.

Map of the whole room: long parts first, short ones later

For KZ-010, it is useful to sort segments by length.

For example:

• A = 2350;

• B = 1700;

• C = 1650;

• D = 950;

• E = 850.

MDF 2600

First A:

• plank 1 → 2350, remainder 250.

Next B:

• plank 2 → 1700 + 850 = 2550.

C:

• bar 3 → 1650 + 950 = 2600.

Total:

3 planks.

Beech/oak 2400

A = 2350 takes up one plank almost completely.

B + E:

1700 + 850 = 2550 — do not fit.

C + D:

1650 + 950 = 2600 — do not fit.

Allowed:

• plank 1 → A;

• plank 2 → B;

• plank 3 → C;

• plank 4 → D + E = 1800.

Total:

4 slats.

Practical conclusion

In this particular map, 200 mm of extra MDF length reduce the purchased quantity from four to three.

But this is the result of specific segments, not a universal advantage of the material.

How much does KZ-010 cost in the example with map A–E

According to the current card.

MDF

3 strips:

3 × 3 140 = 9 420 rub.

Beech

4:

4 × 7 200 = 28 800 rub.

Oak

4:

4 × 11 120 = 44 480 rub.

This is the product cost of the cornice, excluding:

• delivery;

• packaging;

• finish;

• installation;

• consumables.

Why these amounts cannot be compared as equivalent materials

MDF, beech, and oak serve different aesthetic purposes.

The calculation shows the price of the card within the selected material.

When two short segments are more advantageous than one continuous cornice

Sometimes a gap around the air conditioner looks like a loss of integrity, but in fact it makes the project and service better.

Let's imagine:

• wall 4600 mm;

• the air conditioner unit and service area occupy the central section;

• on the left, KZ‑010 is needed for 1700 mm;

• on the right — 1650 mm.

If there were no air conditioner, for MDF one could build a long continuous line with one joint. After installing the unit, two independent parts appear.

What we gain

• both segments are shorter than one product bar;

• each part can be made solid;

• the air conditioner service remains accessible;

• two endings become deliberate.

What we lose

• two open ends appear;

• the cornice is no longer perceived as continuous along this wall.

When this is better

When two clean finished ends look neater than a tight KZ-010 "bridge" over the air conditioner with a questionable service gap.

When it is more appropriate to choose a more compact ceiling profile instead of KZ-010

If after all checks KZ-010 remains too close to the block, there is no need to keep it at any cost.

Can wooden ceiling cornices be compared by actual wall dimension and projection?

What to look for in an alternative

• smaller height on the wall;

• smaller projection;

• appropriate scale;

• required material;

• length of the strip.

Why a more compact profile is sometimes better than a gap

If KZ-010 has to be interrupted at every wall with an air conditioner, while another cornice runs continuously, a more compact model can provide stronger architecture for the entire room.

When keeping KZ-010 still makes sense

If it is part of a unified joinery system:

• door portals;

• high baseboard;

• moldings;

• Panels.

Then a deliberate break at the air conditioner may be better than changing the model throughout the room.

The air conditioner is 75 mm from the ceiling, but only at one point: what to measure in practice

Often, the "75 mm" is taken from a single measurement.

This is a weak foundation.

Measure at least at three points

• upper left corner of the unit;

• the center;

• top right corner.

For example:

• 76 mm;

• 74 mm;

• 72 mm.

For KZ-010 66 mm nominal fields:

• 10;

• 8;

• 6 mm.

The right point is critical.

Why the block may hang not perfectly parallel to the ceiling

Causes:

• the ceiling has a slope;

• Mounting plate is positioned differently;

• the wall is uneven.

What to use in the calculation

Dmin — the minimum actual distance from the unit to the ceiling.

Then:

Ggeo,min = Dmin − 66.

Only this dimension makes sense as the strictest static clearance.

If the ceiling is a stretch ceiling: KZ-010 and the air conditioner form an even more complex assembly

If there is a stretch ceiling nearby, the following must be considered separately:

• wall profile of the ceiling;

• embedded insert;

• KZ‑010 mounting;

• air conditioner route;

• unit mounting plate.

Why KZ-010 cannot be attached to the fabric

The cornice requires a reliable base.

The stretch fabric is not a load-bearing surface.

What to check

• where the wall baguette of the ceiling runs;

• whether the cornice fasteners fall into it;

• whether there is a prepared embedded element;

• whether KZ‑010 obstructs access to the indoor unit.

Why a stretch ceiling amplifies the 9 mm problem

The ceiling construction profile and the actual fabric line may differ from the "ideal ceiling" in the project. A real measurement is needed after the ceiling is completed.

If KZ-010 is already purchased and 9 mm is insufficient for service

Purchasing does not mean the profile must necessarily be installed above the unit.

There are several ways to use the already purchased KZ-010.

Run along the other walls

The air conditioner becomes a deliberate break.

Finish at the architectural boundary

For example:

• by the window;

• near the cabinet;

• by the portal.

Use the leftovers on another wall

After the break, the cutting layout changes, but the material may not be lost.

Do not trim the cornice "in place" around the block

A deep individual cutout often worsens the profile more than a well-executed break.

How to accept KZ-010 after delivery before the first cut

Before cutting, check:

• article number;

• material;

• cross-section 66×51 mm;

• length 2400/2600 mm;

• "Prestige" quality;

• surface preparation;

• straightness;

• end faces;

• transport damage.

First assign long parts

If there is a 2350 mm segment:

• MDF 2600;

• Beech/oak 2400

must be reserved for it before cutting short sections near the air conditioner.

Why a short section cannot be cut first

Suppose the craftsman cut 700 mm from a 2400 mm oak plank.

Remaining:

1700 mm.

After this, a solid 2350 mm piece is no longer possible.

Rule

long segments → medium → short → test pieces.

How to finish two ends of KZ-010 near the air conditioner

If the cornice is interrupted, the two ends become a noticeable part of the interior.

Straight finished end face

The simplest.

Required:

• even cross cut;

• polishing;

• finish.

Return to wall

A short piece covers the cross-section.

Advantages:

• the profile looks complete;

• the large open end shape is not visible.

Disadvantages:

• additional cutting;

• more miter joints.

  How to compare 9 mm with the requirement in the instructions of a specific air conditioner

  After the geometric calculation, you need to obtain one value from the unit's documentation:

  Smanual — minimum free space above or minimum distance to an obstacle, if the manufacturer specifies it.

  Then the initial check looks like this:

  Ggeo,min ≥ Smanual.

  In our original example:

  Ggeo = 9 mm.

  If the instructions for a specific model require more than 9 mm above, the continuous KZ‑010 immediately fails this filter.

  Why this is only the first filter

  Even if:

  Ggeo ≥ Smanual,

  you need to separately check:

  • opening the lid;

  • filters;

  • service;

  • the second dimension of KZ‑010.

  That is, meeting the minimum installation figure does not cancel the dynamic check.

  Example from official documentation of another manufacturer

  For some Daikin FAQ series wall-mounted indoor units, the official reference documentation specifies an upper mounting clearance of 3½ inches, which is approximately 89 mm.

  This figure does not automatically apply to your air conditioner and is not used as a standard in the article. It is needed only as a clear demonstration: real manufacturer requirements can be an order of magnitude greater than the nominal 9 mm.

  Another model may have a different value. Therefore, finding the exact instruction manual is not a formality, but a key technical step.

  Three levels of KZ-010 compatibility with an already installed air conditioner

  To avoid mixing different checks, it is convenient to divide them into three levels.

  Level 1. Static geometry

  The cornice and the closed housing do not physically intersect.

  For the original scheme:

  75 − 66 = 9 mm.

  Result:

  Static intersection is nominally absent.

  This is not yet "suitable."

  Level 2. Operational compatibility

  Checked:

  • air intake;

  • normal operation of the unit;

  • absence of obstruction in the standard air zone.

  Level 3. Service compatibility

  Checked:

  • cover;

  • filter;

  • removable panels;

  • access to fasteners;

  • possibility of full maintenance.

  Why the third level is key for a decorative unit

  A user can see the beautiful KZ-010 for years, but one impossible filter cleaning turns the decorative solution into a constant problem.

  If the air conditioner instruction manual is lost: how to restore the original data without guessing

  An already installed unit was often purchased several years ago, and the paper manual is lost.

  Find the exact model designation

  Usually the model is indicated:

  • on the side sticker;

  • under the front cover;

  • in the app/remote control;

  • in the installation documents.

  A full index is needed, not just the brand and series.

  Search for the official manual

  It is better to use the manufacturer's website or the official technical database.

  You cannot take the first image from search results for a "similar white block."

  If the documentation could not be found

  Before installing KZ-010, you need to contact a service specialist who can assess the specific indoor unit.

  Why the size of a similar model is insufficient

  Even with the same body width, the following may differ:

  • filter;

  • cover hinge;

  • air intake;

  • mounting plate.

  The air conditioner is already working: can you check the template's effect on the air intake before purchasing

  Yes, but only as an additional practical test, not instead of the instructions.

  How to conduct

  1. Install the lightweight KZ-010 template in the project position.

  2. Make sure it is securely fastened and cannot get into the fan/unit.

  3. Turn on the air conditioner in normal mode.

  4. Listen to see if the intake noise changes unusually.

  5. Check if the template vibrates.

  6. After that, still perform a service check.

  What not to do

  It is not allowed based on subjective feeling:

  "the air seems to flow normally"

  to cancel the requirements of the instructions.

  A practical test only shows an obvious conflict.

  How to check the first finishing section KZ-010 before installing the entire room

  If it is decided to interrupt the cornice at the air conditioner, it is worth first making one short control piece.

  Why

  It allows you to check:

  • the real end;

  • visual indentation;

  • color;

  • proximity to the white body;

  • scale of 66 mm.

  Order

  1. make a template.

  2. Approve the end point.

  3. Make one end face.

  4. Perform the finish.

  5. Temporarily install.

  6. Open the cover and filter.

  7. Only after this, replicate the second side.

  Why this is especially useful for oak

  An error in one finishing end on an expensive long whip can change the entire cutting map.

  Inspection after final installation and painting

  Final acceptance is carried out not only on a dry template.

  After installing KZ-010, you need to again:

  • measure the minimum gap;

  • open the cover;

  • remove the filters;

  • check the service;

  • turn on the air conditioner.

  Why repetition is needed

  The actual position of the cornice differs from the mock-up by:

  • installation layer;

  • actual fit;

  • finish treatment;

  • local wall unevenness.

  If contact appears after finishing

  No need to immediately file down the cornice.

  First, determine the cause:

  • the profile is shifted;

  • air conditioner cover has play;

  • the unit is installed not parallel;

  • end face was incorrectly selected.

  Only then adjust the specific unit.

  When instead of KZ-010 it is better to choose another wooden ceiling cornice

  If 66 mm along the wall does not leave the required upper service clearance, the correct alternative is not to "squeeze" KZ-010, but to choose another profile.

  In the category Wooden ceiling cornices... there are models with other cross-sections.

  What to compare

  Not only the appearance.

  Need to check:

  • height along the wall;

  • projection along the ceiling;

  • length;

  • material;

  • corner geometry;

  • compatibility with the existing air conditioner.

  Why "shorter in height" is not always automatically better

  Another profile may have a larger forward projection and hit the lid's trajectory.

  Therefore, the entire cross-section is compared, not just one number.

  When it makes sense to buy a wooden cornice of a different model

  if:

  • KZ-010 does not pass service;

  • relocating the air conditioner is not justified;

  • a continuous line is essential;

  • a more compact profile visually fits.

  Then you can buy a wooden cornice Only after comparing the actual dimensions.

  Wooden trim and air conditioner: why all adjacent lines should be calculated together

  KZ-010 rarely exists alone.

  The interior may include:

  • window casings;

  • door portals;

  • wall moldings;

  • high baseboard.

  If the cornice is interrupted by the air conditioner, the upper composition must remain connected to the rest of the trim.

  For the overall assortment, it is useful Wooden trim.

  What to check

  If KZ-010 ends before the unit, doesn't it appear:

  • short meaningless section before the trim;

  • different axis with the window portal;

  • conflict with the molding on the wall.

  Why this affects cutting

  Changing the endpoint by 100–200 mm can:

  • provide a useful leftover;

  • remove a separate whip;

  • change the visible end face.

  Therefore, the final point is chosen not only by the service minimum, but also by architecture.

  What to send to the STAVROS manager and the air conditioner installer

  For the order, two data sets are needed.

  To the STAVROS manager

  • SKU KZ-010;

  • material;

  • 66×51 mm;

  • wall lengths;

  • number of corners;

  • selected air conditioner bypass scenario;

  • quantity 2400/2600 mm;

  • finish.

  To the air conditioner service specialist

  • unit model;

  • photo of the installed unit;

  • distance Dmin to ceiling;

  • template KZ-010;

  • intended location of the ends.

  Ready-made wording

  "Indoor unit model ___ is already installed; minimum distance from the housing to the ceiling is ___ mm. We plan KZ-010 66×51 mm. Please confirm whether the standard air intake, lid opening, filter removal, and service remain possible with this profile. We plan the cornice continuous / with a gap of ___ mm".

  After technical confirmation, you can buy KZ-010 66×51 mm in the calculated quantity.

  Errors when ordering KZ-010 over an already installed air conditioner

  Error 1. Considering 75−66=9 as sufficient proof

  This is only a geometric gap.

  Error 2. Not knowing the air conditioner model

  It is impossible to verify the manufacturer's requirements.

  Error 3. Checking only the air intake

  The cover or filter may press separately.

  Error 4. Checking only the closed cover

  The conflict occurs during movement.

  Error 5. Gluing the cornice and "checking later"

  After installation, correction becomes expensive.

  Error 6. Trimming KZ-010 locally under the cover

  The profile loses its geometry.

  Error 7. Run the cornice behind the block without service

  Dismantling the air conditioner becomes more difficult.

  Error 8. Make two random short cuts on the sides

  Better one deliberate break.

  Error 9. Calculate the room by the total perimeter

  The break at the air conditioner creates independent parts.

  Error 10. Calculate MDF 2600 and then replace with oak 2400

  The quantity may change.

  Error 11. Not accounting for ceiling unevenness

  The minimum gap turns out to be less than 9 mm.

  Error 12. Not checking the route

  The cornice crosses the box or access.

  Error 13. Do not process open ends

  Especially noticeable on oak and MDF under enamel.

  Error 14. Choose a different profile only by height

  Its overhang may conflict with the lid.

  Error 15. Buy KZ-010 before service confirmation

  First the air conditioner unit, then the product.

  Four boundary scenarios: when 75 mm changes to 80, 70, or 66 mm

  A small change in distance to the ceiling greatly changes the meaning of KZ‑010.

  D to ceiling	KZ-010 on the wall	Nominal Ggeo	Preliminary meaning
  80 мм	66 мм	14 мм	Geometrically freer, but instructions are still mandatory
  75 мм	66 мм	9 мм	original boundary scenario
  70 мм	66 мм	4 мм	extremely dense geometry
  66 мм	66 мм	0 мм	profile and block nominally converge along the line

  Why even 80 mm do not guarantee installation

  Additional 5 mm do not cancel:

  • manufacturer requirements;

  • lid trajectory;

  • filter;

  • second profile dimension.

  What does 70 mm mean

  The cornice leaves only 4 mm of static gap. Any unevenness in the wall or ceiling can eliminate it completely.

  What does 66 mm mean

  This is no longer a "small gap," but a zero nominal remainder. A continuous KZ‑010 above the block without changing the assembly has virtually no geometric space.

  Why this table

  It shows why the measurement must be taken after installing the air conditioner and ceiling. A tape measure error of a few millimeters here is comparable to the entire remaining space.

  Photo documentation before ordering: which four shots really help

  Before ordering KZ‑010, it is useful to take not one general photo of the room, but four technical shots:

  1. air conditioner entirely with a tape measure from ceiling to top edge;

  2. close-up of the left and right upper corners of the unit;

  3. lid in the maximally open position;

  4. filter in the process of removal.

  If the route goes upward, a fifth frame is needed with its duct and the nearest ceiling zone. Such photos allow the furniture maker, installer, and manager to discuss the same node, rather than different ideas about “75 mm.”

  It is especially useful to attach a paper template of 66×51 mm to the photo. Then the frame immediately shows where the lower line of KZ‑010 will be and how close the lid passes to it. This does not replace measurement and instructions, but sharply reduces the risk of misinterpretation from a regular perspective photo.

  Final procurement specification for KZ-010

  Before payment, it is useful to fill in one line:

  KZ‑010 / 66×51 mm / material ___ / Dmin to ceiling ___ mm / instruction requirement from above ___ mm / lid opens yes/no / filter removes yes/no / air intake free yes/no / cornice scenario continuous or broken / segments ___ / slats 2400/2600 ___ pcs. / finish ___.

  What the specification must prove

  • the real air conditioner model is known;

  • 9 mm is not used as a universal standard;

  • service cycle completed;

  • layout calculated after scenario selection;

  • material selected considering length.

  If remains:

  "the air conditioner hangs approximately seven centimeters,"

  the order is not ready yet.

  Final decision tree: can KZ-010 be installed with 75 mm to ceiling

  Step 1. Is the 75 mm distance measured at multiple points?

  • no → measure;

  • yes → use minimum.

  Step 2. Does KZ-010 take up 66 mm along the wall in the design orientation?

  • yes → calculate the nominal remainder.

  Step 3. Is the remainder equal to 9 mm?

  This is only geometry; the following steps are mandatory.

  Step 4. Is the exact air conditioner model known?

  • no → find the marking;

  • Yes → continue.

  Step 5. Does the instruction allow the actual space above?

  • no → exclude continuous KZ-010;

  • Yes → continue.

  Step 6. Is the air intake free?

  • no → change the profile/gap;

  • Yes → continue.

  Step 7. Does the lid fully open with the template?

  • no → change the node;

  • Yes → continue.

  Step 8. Are the filters removed as standard?

  • no → break/another profile;

  • Yes → continue.

  Step 9. Is full service possible?

  • no → increase access;

  • Yes → continue.

  Step 10. Is a continuous or interrupted scenario resolved?

  • no → make a front layout;

  • Yes → continue.

  Step 11. Are the 2400/2600 segments recalculated?

  • no → do not buy around the perimeter;

  • Yes → continue.

  Step 12. Only after this, place the order.

  FAQ

  What size is KZ-010?

  66×51 mm in cross-section. MDF has a length of 2600 mm, beech and oak — 2400 mm.

  How much does KZ-010 take up on the wall in this calculation?

  66 mm.

  If the air conditioner is 75 mm from the ceiling, how much nominally remains?

  9 mm: 75−66=9.

  Do 9 mm mean that installation is possible?

  No. You need to check the instructions, air intake, cover, filters, and service.

  What gap is needed above the air conditioner?

  The one required by the manufacturer of the specific model. There is no universal number for all wall-mounted units.

  Where is the air intake on the air conditioner?

  Depends on the model. It is often associated with the top or top-front area, but the exact design is checked in the documentation.

  Can the KZ-010 interfere with opening the lid?

  Yes, if the lid enters the profile volume when lifted.

  How to check the filter?

  With the KZ-010 template, fully remove the filter in the standard way and put it back.

  Can the curtain rod be run continuously above the unit?

  Only after confirming all operational and service conditions.

  Can the KZ-010 be interrupted before the air conditioner?

  Yes. This is one of the main safe scenarios.

  Can KZ-010 be routed behind the air conditioner?

  For an already installed unit, it is not advisable to recommend this option without an agreed dismantling and service scheme.

  What to do with the route?

  Check whether it crosses the installation zone of KZ-010. General ways to arrange the route are covered in a separate STAVROS article.

  Can a niche be cut out in KZ-010 for the route?

  Only after checking the cross-section and an agreed drawing. Deep random sampling can damage the profile.

  Which material should be chosen?

  MDF — for covering enamel; beech and oak — for wooden finishes. The geometry must fit first.

  What is the length of KZ-010 made of MDF?

  2600 mm.

  What is the length of oak and beech?

  2400 mm.

  How to calculate the number of planks?

  By individual segments after deciding whether the cornice runs continuously or is interrupted at the air conditioner.

  When does the total length give an incorrect answer?

  When long independent parts do not fit in pairs into one plank. For example, four segments of 1700 mm require four rods, although dividing the sum may show three.

  When is it better to choose a different cornice?

  When KZ‑010 does not leave standard service space, a more compact profile allows maintaining a continuous top line.

  Where to order KZ‑010?

  After checking the air conditioner — in the product card of the specific STAVROS item.

  Short conclusion

  Formula:

  75 − 66 = 9 mm

  is useful only as a first geometric filter. It is not permission to install KZ‑010.

  Correct sequence:

  exact air conditioner model → minimum actual D to ceiling → manufacturer's instructions → air intake → cover → filter → full service → template 66×51 mm → continuous or interrupted cornice → map 2400/2600 → order.

  If the instructions and physical test confirm operation with such geometry, KZ‑010 can be used. If the air intake is blocked, the cover hits, or the filter cannot be removed, it is better to end the cornice before the unit, resume it after, or choose a more compact model.

  After the final check, you can order a wooden cornice KZ-010 already as a calculated interior element, not as a profile that "seems to fit in the remaining 9 mm".
